Which VHF marine channel is specifically dedicated to DSC?

The correct answer is associated with the Digital Selective Calling (DSC) system used in maritime communications. VHF marine channel 70 is specifically allocated for DSC distress and safety communications. This channel plays a crucial role in enhancing the safety of maritime operations by allowing vessels to send automated distress signals, which include their location and identity, without the need for voice communication.

Channel 70 is reserved for these digital transmissions and is monitored continuously by ships and coast stations for emergency situations. Other channels, such as 16, are primarily used for voice communications as well as emergency broadcasts, but they do not handle DSC traffic. Understanding the purpose and usage of these various VHF channels is essential for effective communication and safety at sea.
